該綜述基于近年來時玉舫研究組對于間充質(zhì)干細胞免疫學(xué)的主要研究成果和該領(lǐng)域的進展，系統(tǒng)闡述了間充質(zhì)干細胞與免疫系統(tǒng)的相互作用及其機制,，疾病發(fā)生過程中的作用,，并對創(chuàng)傷愈合的影響以及其在臨床應(yīng)用中的廣闊前景，提出了此領(lǐng)域內(nèi)亟需解答的關(guān)鍵問題,。

間充質(zhì)干細胞（mesenchymal stem cells,，MSCs）是骨髓中除造血干細胞以外的一種組織干細胞，廣泛分布于骨髓,、肝臟,、脂肪、臍帶等多種組織中,，具有強大的自我更新能力和多向分化潛能,。因此，間充質(zhì)干細胞移植在再生醫(yī)學(xué)領(lǐng)域具有廣闊的應(yīng)用前景,。同時,，作為一種重要的免疫調(diào)節(jié)細胞，MSCs在炎癥細胞因子刺激后對免疫系統(tǒng)表現(xiàn)出很強的調(diào)節(jié)作用,，所以MSCs有望應(yīng)用于治療系統(tǒng)性紅斑狼瘡等自身免疫疾病,。在時玉舫研究員的帶領(lǐng)下，該研究組科研人員對間充質(zhì)干細胞與免疫系統(tǒng)的相互作用進行了系統(tǒng)的研究工作,，闡明了間充質(zhì)干細胞對于免疫系統(tǒng)具體的調(diào)節(jié)機制,，極大地豐富了人們對于間充質(zhì)干細胞的理解，在該研究領(lǐng)域成果顯著,，受到了同行的廣泛關(guān)注,。

How mesenchymal stem cells interact with tissue immune responses

Mesenchymal stem cells （MSCs）, also called multipotent mesenchymal stromal cells, exist in almost all tissues and are a key cell source for tissue repair and regeneration. Under pathological conditions, such as tissue injury, these cells are mobilized towards the site of damage. Tissue damage is usually accompanied by proinflammatory factors, produced by both innate and adaptive immune responses, to which MSCs are known to respond. Indeed, recent studies have shown that there are bidirectional interactions between MSCs and inflammatory cells, which determine the outcome of MSC-mediated tissue repair processes. Although many details of these interactions remain to be elucidated, we provide here a synthesis of the current status of this newly emerging and rapidly advancing field.
